Abstract

The invention discloses a method for realizing an owner-drawing control. The method comprises steps: receiving control operation of display contents; when a content control of the display contents is a Windows window content control, transferring the control operation to a scroll-bar control through a parent window of the content control, to make the scroll-bar control complete control response operation of the display content according to the control operation. The invention also discloses a device for realizing an owner-drawing control. The method and the device realize complete owner-drawing operation on a scroll-bar in a control, and improve customization property and applicability of an owner-drawing control.

Description

technical field [0001] The invention relates to the technical field of software development, in particular to a method and a device for realizing a self-drawing control. Background technique [0002] In the Windows window, controls such as list (list) and tree (tree) can store and display a large amount of data. When the amount of data to be displayed is large, it cannot be displayed at one time in the display interface due to the limitation of the size of the control interface. When all the data is divided into multiple pages to display, and scroll to achieve mobile page operations. At present, the scroll bar of the content control generally includes: use the default scroll bar style of the system. Create a fully self-drawn control library, both content controls and scroll bars are self-drawn. [0003] However, due to Windows' limitations on the encapsulation of self-drawing controls, when using the Widnows window content control, the scroll bar is located in the content ...
